    Important: New Screwbutton Ring Design

    Plexi Requirements
    This pushbutton comes with a new screwbutton ring. Seimitsu is replacing its original clear or milky white screwbutton ring with a black plastic alternative. Thinner than the original model, the ring is more compact for tight spaces, and easier to screw on or off.

    Our photos reflect the older model, due to the amount of photos needed to replace them, we are temporarily adding a note until new photos can be taken.

    The Seimitsu PS-14 GN is a solid color 30mm threaded button with clear screw ring. The PS-GN is often used for arcade cabinets with a thick control panel (15mm or 0.59"), but can also be used in metal panels because of the screw ring.  Unlike the PS-14-G snapbutton, the PS-14-GN has a convex plunger. This pushbutton is available in 7 colors including black (K/K), along with with a black rim/color plunger variation in 6 colors. The PS-14 GN uses the Seimitsu PS-14-G Button Micro Switch. Please see our product photo gallery for full specs.

    By default, Seimitsu PS-14-G microswitch requires 1.0N or 0.2 LBF (pounds force) to each button. 

    The MM9-4-25N adds an extra .08 LBF (pounds force), for a total of 0.28 LBF.  The result is a light, but firm button input requirement that accelerates its the button cap's return to neutral. 

    The MM9-4-50N adds an extra .16 LBF (pounds force), for a total of 0.34 LBF, resulting in a much firmer button input requirement that quickly pushes the button cap's to neutral position, ready for the next press.

    This is desirable to some who appreciate using more deliberate input force and a bit less sensitivity than Sanwa's SW-68 offers. Now, you can save 25 cents off the regular price of the MM9-4 series spring when you choose one of the high tension springs from the options list.

    Silencer is our 1mm-thick foam washer that helps to dampen the loud sounds common with tapping on the button plunger.  It conforms to the internal housing of many Sanwa or Seimitsu-style 30mm pushbuttons.

    Silencer Installation

    installing the Silencer foam pads into a Sanwa or Seimitsu pushbutton is straightforward.  Place the washer - plastic film side down - into the button housing.  Align the small tabs so that they stick out of the holes on each side of the housing.  For Seimitsu PS-15, and Hori Hayabusa low profile pushbuttons, snip the tabs off with scissors and place into the housing.

    24 vs 30mm

    When processing orders, a frequent mistake we found among new players is choosing the wrong size for action buttons, such as punch and kick.

    Within the fighting game genre, Japanese arcade buttons commonly consist of two diameter sizes: 24 millimeter and 30 milllimeter (mm). In most configurations, 30mm represents your action button.  These are front facing, appearing most prominent on your Fightstick control panel.  Option button, such as "Start", "Select", or more recently "Option", "Touch", or "Share" are usually 24mm.

    UPDATE: Owners of Neo Geo AES Joysticks will need 24mm pushbuttons instead of 30mm (Thanks SRK's DEZALB)

    Below is a visual representation of a common Fightstick control panel.  Throughout this article, we will mark 24mm in green, and 30mm in Orange.

    Checking the Proper Size

    button-30mm.pngAnother way that players can misinterpret the pushbutton size is by measuring the pushbutton plunger.  Have a look at the diagram at right.

    The plunger - the part that you press down to represent an input - is 25mm or a bit smaller in most 30mm pushbuttons.  Often this leads to the conclusion that one needs a 24mm button and not 30mm.

    Similarly measuring the button rim can lead to confusion, as it is intentionally larger than the button hole it is placed in.  You don't want to use these measurements.  Instead, review the button housing diameter, or the hole the button will be placed in.  You can do this with a caliper - a digital caliper is often quite helpful for this and other arcade-related projects.

    Control Panel Configuration

    Most Fightsticks from MadCatz, Hori, Qanba, and similar will use these two sizes.  How the buttons are used will depend on the model joystick that you own. Over time, we'll provide example configurations for specific popular Fightstick models and arcade cabinets using the color key for 24mm (green) and 30mm (orange).  We'll also expand the key for future models if another size is introduced, and we offer for sale.

    1. Good, but not great

      In terms of feel, they require a bit more force to actuate than a sanwa button and have a nice, strong bounce back when releasing the button, but personally these buttons feel rather mushy on the down press. I somewhat agree with reviewer Ted's comparison to crown mx buttons, though crown mx buttons have a far superior feel to them. Seimitsu buttons are good and don't feel terrible, but my honest recommendation would be to spend a little more and go with crown 202's instead; you'd get a similar feel without the mushiness on the down press. Your mileage may vary though, since this is all personal preference after all. on Sep 26th 2021

    2. The perfect in between

      Sanwa is viewed as the standard. And I would agree for shmups and Casual play. They're light and fluffy. Submit Sue's are more Hardy and robust. They take more Force to activate, and they bounced back ever so quicker. So I feel like it's a better competitive/responsive product. I would compare it more to a Crown Cherry MX button then a sanwa. Which is a good thing. I think the crown buttons are the best buttons. Lol. on Jun 25th 2019
